Police say a passenger in the vehicle was pronounced dead at the scene. The driver was airlifted to a Toronto-area hospital with serious injuries.
On Monday morning, OPP identified the victim as Daniel Nicholas Thomson, 32, of Campbellcroft.
The driver — Mathieu Richard, 31, of Whitby — has been charged with impaired driving causing death.
He is scheduled to appear in court in Cobourg on April 6.
